As we mentioned earlier this week, Andretti Autosport has won five of the seven Verizon IndyCar Series races at Iowa Speedway. But the only other IndyCar team that’s won at Iowa will lead the field to green tomorrow night in the Iowa Corn Indy 300 (8 p.m. ET, NBCSN and NBC Sports Live Extra).

Defending series champion Scott Dixon’s two-lap average of 186.256 miles per hour was enough to knock off Target teammate Tony Kanaan’s average of 185.891 mph.

Dixon was able to take advantage of some advice from Kanaan and mutual teammate Ryan Briscoe, who both took their own qualifying runs before him.

“Both TK and Ryan went before us out there, and they thought the track had a bit of understeer,” Dixon said to NBCSN’s Kelli Stavast. “So we were able to make some wing changes on the car – obviously, to get it to turn a little bit better. And it worked out perfectly for us.

“But you never really know sometimes how your car’s gonna be compared to theirs, and putting more front wing in – sitting in a qualifying line, it’s not always something you want to hear because it just makes the car looser. But it was definitely the right call.”

“We haven’t delivered yet, so tomorrow will be the opportunity to redeem what happened last week,” said Kanaan, who continues to search for his first win as a member of the Ganassi camp.

Current series championship co-leader Helio Castroneves will start on the inside of Row 2 thanks to his average of 185.789 mph.

His second lap of 186.809 mph was fast enough to set a single-lap qualifying record for Iowa, but his first lap of 184.575 mph was what kept him from the pole.

Briscoe posted an average of 185.339 mph and will start to Castroneves’ outside on Row 2. Andretti Autosport rookie Carlos Munoz (185.027) and KVSH Racing’s Sebastien Bourdais (184.968) make up Row 3, while Charlie Kimball (Ganassi; 184.743) and Marco Andretti (Andretti; 184.726) will be in Row 4.

Will Power, who shares the championship lead with Penske teammate Castroneves, was first to take a qualifying run and he settled for ninth on the grid (184.683). He’ll be in Row 5 along with Ed Carpenter (184.589).

Are you expecting a better than normal tax refund? Did you get a very nice bonus from your company due to the new tax cut?

Well, if you have a good chunk of change hanging around and potentially can be in Monaco on May 11, you can have a chance to bid on the 1993 McLaren-Ford MP4/8A that the late Ayrton Senna drove in — and won — that year’s Monaco Grand Prix.

We’re not just talking about any race winner. It’s also the same car Senna won his sixth Monaco Grand Prix, and the chassis bears the number six.

It’s also the same car Senna piloted to that season’s F1 championship (his third and final title before sadly being killed the next year) and is the first McLaren driven by Senna that’s ever been sold or put up for auction.

The famed Bonhams auction house is overseeing the sale of the car.

“Any Grand Prix-winning car is important, but to have the golden combination of both Senna and Monaco is a seriously rare privilege indeed,” Bonhams global head of motorsport, Mark Osborne, told The Robb Report.

“Senna and Monaco are historically intertwined, and this car represents the culmination of his achievements at the Monegasque track. This is one of the most significant Grand Prix cars ever to appear at auction, and is certainly the most significant Grand Prix car to be offered since the Fangio Mercedes-Benz W196R, which sold for a world record at auction.”
